Overlay and Split History
In 1997, the 818 area code was split, and the 626 area code was created to serve the San Gabriel Valley region. This split was necessary due to the rapid growth of the population and the increasing demand for phone numbers in the area. In 2017, the California Public Utilities Commission approved an overlay plan for the 818 area code, which introduced the 747 area code as an overlay. This means that 10-digit dialing is now required for all calls within the 818 area code, including local calls.
